摘要/Abstract

摘要： 目的: 探讨能谱CT单能量成像在颌骨骨髓炎病灶显示中的临床应用价值。方法: 回顾性分析在上海交通大学医学院附属第九人民医院诊断为颌骨骨髓炎的12例患者的能谱CT资料,利用GSI Viewer软件重建40、50、60、70、80 keV 单能量值下的图像,分析病灶区每组单能量下的CT值和SNR值,得到最适keV值,与增强MRI图像比较,评估能谱CT成像对周围软组织的显示。采用PASW Statistics 18.0软件包对数据进行统计学分析。结果: 不同单能量值对CT值具有显著影响（P<0.01）,70 keV下的图像质量较好,能谱CT成像能够显示周围软组织受累情况。结论: 70keV条件下的能谱CT单能量图像对颌骨骨髓炎的病灶显示效果最佳,且能谱CT图像能够反映周围软组织情况,对颌骨骨髓炎具有一定的诊断效能。

Abstract: PURPOSE: To explore the clinical application value of energy spectrum CT single energy imaging in displaying lesions of jawbone osteomyelitis. METHODS: Energy spectrum CT imaging data of 12 patients diagnosed with jaw osteomyelitis in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. GSI Viewer software was used to reconstruct the images at 40, 50, 60, 70, 80 keV single energy values. The CT values and SNR values of each single energy group in the lesion area were analyzed to obtain the optimal keV value, and compared with enhanced MRI images to evaluate the display of energy spectrum CT imaging on surrounding soft tissues. PASW Statistics 18.0 software package was used for data analysis. RESULTS: Different single energy values had significant impact on CT values(P<0.01), and the image quality was relatively good at 70 keV. Energy spectrum CT imaging could display the involvement of surrounding soft tissues. CONCLUSIONS: Energy spectrum CT single energy image under the condition of 70 keV has the best display effect on the lesions of jawbone osteomyelitis, which can reflect the surrounding soft tissue situation, with certain diagnostic efficacy for jawbone osteomyelitis.

Key words: Jawbone osteomyelitis, Energy spectrum CT, Single energy image, Diagnostic efficacy
